The Effect of OnabotulinumtoxinA on the Symptoms and Quality of Life in Women with Urge Urinary Incontinence

Objectives: To determine the effect of OnabotulinumtoxinA intradetrusor injection on quality of life (QOL) and symptoms of women with urge urinary incontinence. Methods: Twenty five postmenopausal patients with urge urinary incontinence, underwent cystoscopy and 200 U OnabotulinumtoxinA intradetrusor injections (0.5 cc at each injection). The effects of botox have been evaluated on urge urinary incontinence and quality of life. Results: The mean urge urinary incontinence per day was 7.25 which decreased to 2.87 (month 1) and 3.12 (month 6); P value = 0.019. The mean of nocturnal episodes was 3 which decreased to 0 and 1in the first and sixth months, respectively (P = 0.007). Baseline mean I-QOL total score was 43.37 which reached 82.12 (month 1) and 78.87 (month 6); P < 0.001. Conclusions: OnabotulinumtoxinA significantly decreased urinary urge incontinence and nocturia at month 1 and 6. The quality of life of patients has improved.
